The default gateway address must be 192.168.10.1.

The ip default-gateway command has to be issued in the VLAN interface configuration mode.

The VLAN IP address and the default gateway IP address are not in the same network.

The no shutdown command was not issued for VLAN 1.

The local DNS server is not functioning correctly.
